The maternal relationship between Christina Jonsdotter and her son Carl Carlsson Utterström is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant FG.

The segmental (via DNA segment triangulation) and total DNA shared between FG and other confirmed descendants of Olof Sundell/Dordi Nilsdotter is consistent with the expected ranges for their respective relationships. Since FG descends from Olof Sundell/Dordi Nilsdotter through Christina Jonsdotter and her son Carl Carlsson Utterström, the presence of significant shared DNA between FG and other known descendants of Olof Sundell/Dordi Nilsdotter validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Olof Sundell/Dordi Nilsdotter through Christina Jonsdotter to Carl Carlsson Utterström, and ultimately to FG, confirming this direct ancestral connection through multiple generations.
